Abstract

The evolution of texture in the β-phase of a two-phase (O+B2) titanium–aluminide Ti–22Al–25Nb (at.%) alloy during thermo-mechanical processing in single β-phase-field has been studied. Variations in microstructure and texture have been observed as a result of variation in the amount of rolling deformation for a given rolling temperature. The evolution of crystallographic texture in the β-phase can be understood by considering the increase in dynamic recrystallisation to which is associated a grain size reduction.
